Selecting a row in DataGridView programmatically

Question

How can I select a particular range of rows in a DataGridView programmatically at runtime?

Answer 1

 .ClearSelection(); ----------------------------------------------------1
 foreach(var item in itemList) -------------------------------------------------------2
 {
    rowHandle =.LocateByValue("UniqueProperty_Name", item.unique_id );--3
    if (rowHandle != GridControl.InvalidRowHandle)------------------------------------4
    {
        .SelectRow(rowHandle);------------------------------------ -----5
    }
  }

1. Clear all previous selection.
2. Loop through rows needed to be selected in your grid.
3. Get their row handles from grid (Note here grid is already updated with new rows)
4. Checking if the row handle is valid or not.
5. When valid row handle then select it.

Where itemList is list of rows to be selected in the grid view.
